Press the Shift button to move the cursor to the left, and the Set Up and Set Down buttons to change the value of each number. 5. Press the Extra Cycle button 6. The unit will reprogram itself with the new Time of Day. Manually Initiating a Regeneration 1. When timer is In Service or Stand By, press the Extra Cycle button for five (5) seconds on the main screen to force a manual regeneration if another unit is not in regeneration. 2. The timer reaches Regeneration Cycle Step #1. 3. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (if active). 4. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (if active). 5. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (if active). 6. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #5 (if active). 7. Press the Extra Cycle button once more to advance the valve back to In Service Timer Operation During Regeneration In the Regeneration Cycle step display, the timer shows the current regeneration cycle number the valve is on, or has reached, and the time remaining in that step. Once all regeneration steps are complete the timer returns to In Service and resumes normal operation. Example: 12 Minutes Remaining in Cycle 1 (Back Wash) Press the Extra Cycle button during a Regeneration Cycle to immediately advance the valve to the next cycle step position and resume normal step timing. Flow Meter Equipped Timer During normal operation the Time of Day screen alternates with the error screen (if errors are present). As treated water is used, the Volume Remaining display counts down from the calculated system capacity to zero. When this occurs a Regeneration Cycle begins if no other units are in regeneration. Page 4

5 Timer Operation Timer Operation During Programming The timer enters the Program Mode in standby or service mode as long as it is not in regeneration. While in the Program Mode the timer continues to operate normally monitoring water usage. Timer programming is stored in memory permanently. Timer Operation During A Power Failure During a power failure all timer displays and programming are stored for use upon power re-application. The timer retains all values, without loss. The timer is fully inoperative and any calls for regeneration are delayed. The timer, upon power re-application, resumes normal operation from the point that it was interrupted. NOTE: A flashing Time of Day display indicates a power outage. Remote Lockout The timer does not allow the unit/system to go into Regeneration until the Regeneration Lockout Input signal to the unit is cleared. This requires a contact closure to activate the unit. The recommended gauge wire is 20 with a maximum length of 500 feet. See P4 remote inputs in the wiring diagrams in the service manual. Regeneration Day Override Feature If the Day Override option is turned on and the valve reaches the set Regeneration Day Override value, the Regeneration Cycle starts if no other unit is in Regeneration. If other units are in regeneration, it is added to a regeneration queue. This occurs regardless of the remaining volume available. Page 5

6 System Operation In Service The system operates as part of a multi-valve regeneration system. Each valve in the system will have an active flow meter input, even in stand by. The number of valves in service depends on the flow rate. Examples of a Four-Unit System: Page 6

38 Troubleshooting Detected Errors If a communication error is detected, an Error Screen will alternate with the main (time of day) screen every few seconds. All units In Service remain in the In Service position. All units in Standby go to In Service. Any unit in Regeneration when the error occurs completes Regeneration and goes to In Service. No units are allowed to start a Regeneration Cycle while the error condition exists, unless they are manually forced into Regeneration. When an error is corrected and the error no longer displays (it may take several seconds for all of the units in a system to stop displaying the error message), the system returns to normal operation. NOTE: During the error condition the control continues to monitor the flow meter and update the volume remaining. Once the error condition is corrected all units return to the operating status they were in prior to the error. Regeneration queue is rebuilt according to the normal system operation. Or, if more than one unit has been queued for regeneration, then the queue is rebuilt according to which one communicates first. Cause A. One or more units have a missing or bad communication cable. B. One or more units has a communication cable plugged into the wrong receptacle. C. One or more units is not powered. C. Power all units. Programming Errors Correction A. Connect the communication cables and/or replace. B. Connect the communication cable as shown in the wiring diagrams. During the error condition the control continues to monitor the flow meter and update the remaining capacity. Once the error condition is corrected all units return to the operating status they were in prior to the error and regeneration is queued according to the normal system operation. If reprogramming the unit in the Master Programming Mode clears the error, the volume remaining may be reset to the full unit capacity (i.e. as though it were just regenerated). 1. All units in standby go In Service. 2. Any unit in regeneration when the error occurs completes regeneration and goes to In Service. 3. No units are allowed to start a regeneration cycle while the error condition exists. When the problem is corrected and the error no longer displays (it may take several seconds for all of the units in a system to stop displaying the error message), the system returns to normal operation. Programming Errors Detected: Duplicate unit addresses or numbers Size of system (ex: if sized for a 4 units, and only have 2 units) Display format mismatches Solution: Program the units correctly in the Master Programming Mode. NOTE: If these errors are detected, numbers 1 through 3 on the previous page become true, and the main screen (time of day) will alternate with an error screen. Page 38

39 Troubleshooting Cause A. Any or all of two or more units programmed with the same unit number (Matching Address Error) Correction A. Program the units correctly in the Master Programming Mode B. Flashing/blinking display B. Power outage has occurred C. Format Mismatch (Units have both U.S. and Metric Formats) D. No messages displayed/small black squares appear in display E. Size Error (Units not correctly numbered/more than one unit has the same number assigned) C. Verify all units have same Format selected (all U.S. or all Metric) D. Turn the contrast button on the back of unit until text appears (see Problems Viewing Display/Changing Contrast of Display below) E. Check each unit and verify each as the correct number, and that only one unit has that number F. Com Error (Communication Error) F. Check the wiring of the system and verify it is correct and that all are connected Problems Viewing Display & Changing Contrast of Display If the display cannot be seen, or if a lighter or darker screen is desired, adjust with the small black dial on the back of the unit. It is located in the upper right hand corner. See image below, with the arrow pointing at the dial. Page 39
